The effect of UV beam, which has been emitted from a natural or a manmade source on cells has been studied in previous studies for several times. Radiation of this beam can have different effects on DNA of the cell, cytotoxicity, the structure of cellular proteins and their mechanical properties based on radiation period or frequency. The effect of radiation of two types of beams, namely UVB an...

INTRODUCTION Birds have undoubtedly been colliding with manmade structures ever since humans started building things skyward. The earliest documented instances of collision mortality in this country are from the late 1800's (Coues 1876, Merriam 1885) and the problems continue unabated today. The total avian mortality due to collisions with manmade obstacles is probably greater every year as bui...

Background The historical maps have become a more common and important source of information in administrative work within the cultural heritage sector in Sweden. The usage of historical maps has also increased in untraditional sectors, such as infrastructural planning, as the interest in environmental issues has increased in past years. The character of the historical map is that of;  knowled...

This project focuses on ASAR backscatter change from urban categories as a function of polarisation and incidence angle. Results show more bright scattering points from manmade objects in like-pol than in cross-pol. ASAR AP data acquired with several incidence angles may be used with success to obtain more knowledge about structural properties of certain man-made objects.

SMS [4,6] is an object representation system motivated by the requirements of recognition instead of depiction. It is designed for model invocation, reference frame estimation and matching (roughly as in IMAGINE [5], only with many extensions). It represents strongly visible features and relationships of non-polyhedral manmade objects, integrating curve, surface and volumetric structural descri...
